Title: Magnetic circuit breaker
Inventor: LEE WEN-FONG
IPC: H01H33/66
Filed: 1987-05-08
Abstract: A magnetic circuit breaker includes a vacuum or gas-filled sealed casing 1. Mounted in the casing 1 are a stationary contact 2, a movable contact 4, a linkage 100 connected to the movable contact 4, a tension spring 7 for activating the linkage 100, and a latch 8 controllable by an electromagnet (10-12) or bimetal for normally hindering the linkage 100 from movement resulting from the tension spring 7. A manual set and reset mechanism 200 is provided for moving the movable contact 4 to electrically connect with and disconnect from the stationary contact 2 to thus close and open the circuit. An automatically indicating device 300 is drivable by the linkage 100 to indicate the state of overload or short-circuit when the circuit is converted into the same state. In this case, the linkage 100 is released from the latch 8 by the action of the electromagnet or bimetal so that the movable contact 4 is pulled by the tension spring 7 away from the stationary contact 2 to open the circuit. Two pairs of mutually attractable magnetic members M1 and 61, M2 and 18 are respectively used to transfer motions between the linkage 100 and the manual set, reset mechanism 200, as well as between the linkage and automatic indicating device. Magnetic member M1 is movable by a rotary handle 15 to attract or allow pivoting of the member 61. On overload, member 18 moves to attract magnetic member M2 and bring a trip sign into a window 24. The members M2 and 18 can be replaced by an elongated link from link C3<1>, directly bearing the trip sign. <IMAGE>

Title: Connection device
Inventor: PARSONS MICHAEL CHARLES
IPC: A45F3/04
Filed: 1987-07-03
Abstract: Two elements (30, 40), each having a respective aperture (31, 41) therethrough, are connected together by a device comprising a bridging section (10) from opposite ends of which respective limbs (12, 14) project laterally. At its free end, the first limb (12) has an enlargement (16) which serves to retain the device when it has been inserted, by way of the second limb (14) and bridging section (10), through one of the apertures (31). The second limb (14) is flexible and has, on its side remote from the first limb (12), a protrusion (18) which serves as a catch means to retain the second limb (14) when it has been inserted through the other aperture (41). <IMAGE>
Patent GB-871865-A (GB)
Abstract: 871,865. Electric re-recording systems. SEISMOGRAPH SERVICE CORPORATION. July 24, 1957 [Aug. 23, 1956], No. 23471/57. Class 40 (1). [Also in Groups XL (b) and XL (c)]  Seismic field traces 13, Fig. 1, are re-recorded electrically on to more permanent, or reproducible recording media. The lateral amplitude of the original trace may be followed manually by a follower 19, lateral movement of which varies an impedance such as the variable capacity 25 in the modulating circuit 28 of an oscillator 29 and the modulated output is fed to a selected one of recording heads 34 to make a record on a magnetic tape 15 sharing a common drive with the original trace. In a modication the original trace is followed automatically by means of a light beam and a photo-sensitive device whose output operates a servo system to keep the follower on the trace. In another modification the modulated output alters the intensity of a lamp so that the trace is re-recorded as a variable density trace on a photographic film.

Title: Arrangement for measuring non-ionising radiation
Inventor: WARD DAVID ROBERT
IPC: G01R21/02
Filed: 1989-06-15
Abstract: In an RF radiation measuring probe (1), changes in physical properties of a ferrite absorber (7) are measured by a transducer (8) which transmits signals to a processor module 4 which determines the power flux density of the incident RF field (20). The transducer may be an optical fibre (8, 14) driven by a light source (17) in the processor module, or a piezo-electric crystal. The optical fibre (8, 14) contacts the absorber and determines changes in absorber temperature by measuring phase changes in the optical fibre (8, 14). The piezo-electric crystal (Fig. 2 not shown) indicates contraction or expansion of the absorber by a change in potential difference across one of its faces. <IMAGE>

Filed: 1989-08-18
Abstract: A microprocessor 22 controls a battery selecting circuit 12 in response to signals from a battery presence detector 16 and a charging completion detector 18. The detector 16 senses the affect on the voltage on a battery charging line B+ of the connection thereto of that one of the batteries 23, 25 selected by a relay RY2. Detector 16 may also respond to an excessively high or low voltage on the line B+, (Figs 2,3). Initially battery 23 is selected for rapid charging. If the battery 23 is absent (106), (Fig 4), is removed during its rapid charging (112) or charging completion is sensed (110), the microprocessor 22 selects battery 25 for rapid charging a return to the start of the microprocessor program being affected if the battery 25 is absent (120), is removed during its rapid charging (126), or charging completion is sensed (124). The arrangement may be expanded to charge three or more batteries, in succession. <IMAGE>

Title: Anti-detection device for a radar antenna
Inventor: JACQUES CHRISTOPHE
IPC: H01Q1/42
Filed: 1990-11-26
Abstract: A device, disposed in front of an antenna for forming a radome for example, reduces the possibility of detection of said antenna by minimizing the radar cross section of the antenna without substantially disturbing the radiation of the antenna and, in addition, protects the antenna against the effects of jamming outside its operating frequency band. The material of the radome is constructed to pass only the bandwidth of the antenna and comprises slotted parallel conductive plates. This reduces reflection or jamming at all other frequencies. The varying angles of the radome shape help to reduce transmission of off-boresight angles thereby reducing sidelobe response. The device is made up of three separate elements: a cone 4, a frustrum 5 blending into the base 40 of said cone and a second frustrum 6 blending into the base of said first frustrum. The device closes half of the space in front of the antenna.

IPC: H01Q13/02
Filed: 1991-03-01
Abstract: A circular horn antenna having a wide beam and an extended bandwidth of 6-18 GHz, for use with signals having orthogonal polarization planes.

Title: Spin-on glass processing technique for the fabrication of semiconductor devices
Inventor: OUELLET LUC M
IPC: H01L21/316
Filed: 1992-09-07
Abstract: A method of applying a spin-on glass layer to a substrate is disclosed characterized in that the spin-on glass is applied as a plurality of contiguous thin layers that together form a composite layer. Each thin layer is cured prior to the application of the next layer at a temperature of at least about 300  DEG C, preferably 350 DEG C, for a time sufficient to permit catalyst connection and substantially eliminate volatile residual solvents contained therein. In this way cracking in organic SOGs can be substantially eliminated, and beneficial results can also be achieved with quasi-organic SOGs.

Patent GB-2286919-A (GB)
Title: Radiation sources
Inventor: CHUGG ANDREW MICHAEL
IPC: G21G4/04
Filed: 1994-02-24
Abstract: The intensity of the radiation which impinges upon spacecraft has a directional dependence. In simulating this environment it is necessary to reproduce this directionality at all points in the modelling space. This cannot be achieved efficiently with the single disc source types which are currently available. A system of multiple disc sources has therefore been devised. In order to produce an even and symmetrical distribution of sources about the target, configurations based upon certain Archimedian polyhedra are utilised. Polyhedra with a relatively large number of faces of similar shape and area are the most suitable, particularly the truncated icosahedron (6) and triangularly sub-divided versions of the truncated icosahedron and the snub dodecahedron (9 Fig. 4 not shown).   <IMAGE>
